Radio stations with radio data system (RDS) technology broadcast special program information that only radios with an RDS feature can receive. Between 1994 and 1996, the number of RDS radio stations in Verdland increased from 250 to 600. However, since the number of RDS-equipped radios in Verdland was about the same in 1996 as in 1994, the number of Verdlanders receiving the special program information probably did not increase significantly.

Which of the following is an assumption on which the argument depends?
(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.
(B) In 1996 most Verdlanders who lived within the listening area of an RDS station already had a radio equipped to receive RDS.
(C) Equipping a radio station with RDS technology does not decrease the station's listening area.
(D) In 1996 Verdlanders who did not own radios equipped to receive RDS could not receive any programming from the RDS radio stations that began broadcasting in Verdland after 1994.
(E) The RDS radio stations in Verdland in 1996 did not all offer the same type of programming.

答案是选A，可是这个A选项看不太懂，很迷糊~~

瞎凑热闹
我个人认为A: 很少有人，那些人就是以前从来不接触RDS德人，在1994年后被RDS的广播所辐射到。就是，RDS的听众群在1994年后基本保持不变。

Radio stations with RDS 才能广播一种special program information。
1994－1996，这种 Radio stations 增加了，可是用来接受 RDS 的 radio（设备）却没增加。
得出结论special program information的接收也没又增加。
a大概意思是说，很少有1994年后新开的 RDS station是开在那些之前的RDS station 影响不到的地方。（就是说：新开的station都是在原来那些station能覆盖的范围内）
把a取非，如果大部分新开的station在原来station不能把special program information传送到的地方，那么即使设备没有增加，原来接收不到的special program information的地方的设备现在也能接收的到，那么接收的量也就增加了

文章说：有RDS技术的无线电台只传播RDS收音机才能接受的信息。1994到1996年间，RDS广播站增加了，然后因为RDS收音机数量没变，所以能接受到RDS特殊信息的人就会不会怎么怎家
Which of the following is an assumption on which the argument depends?
意思就是RDS站变多了，RDS收音机没变，怎样得到收听的人数也没变，即突破点在如何建立起RDS收音机数量变化和收听人数变化的关系
(A) Few if any of the RDS radio stations that began broadcasting in Verdland after 1994 broadcast to people with RDS-equipped radios living in areas not previously reached by RDS stations.
意思是很少有新RDS广播站位于之前老RDS广播站覆盖不到的地方，就是说虽然RDS站变多了，但是覆盖范围没有怎么变化，如果覆盖范围大幅度变化，即使RDS收音机数量没变，能够收到特殊信息的RDS收音机也就变多了（注意，这里暗示了一个文章的隐藏条件就是：收音机数量和收听人数的关系，即题目没有规定所有的RDS收音机都在覆盖范围内，及所有RDS收音机的用户都能收到特殊信息，从一点突破选A）
